I would be surprised if that board doesn't have PXE. Check there's not an option saying "LAN" or "ROM", just enable anything that looks network related (making a note of what you have done!).

If it really doesn't have PXE boot capabilities, there are other options. You can either buy a NIC that does support it, perhaps using it with a 90 degree riser if you care about MD flatness. Or, you can generate your own network boot image http://www.rom-o-matic.net/. You can use a CD, floppy, or even USB I believe.

Provide a bit more information about your hardware/BIOS as well please.

1. Did you interrupt it the first time it announced itself to the router, because it just hung there and didn't seem to be doing anything? Because it was doing things.2. In web admin under "Media Directors" did it make one (should be two there now, 1st the hybrid, and second the MD)? If not, run /usr/pluto/bin/Diskless_CreateTBZ.sh again.If so delete it, run /usr/pluto/bin/Diskless_CreateTBZ.sh again, then boot and do not interrupt it.
